Synchronous laser plastic welding machine uses high-power semiconductor laser as its welding light source, which has the advantages offast welding time, low thermal effect and low welding thermal stress, effectively improving production efficiency and welding quality.
- Use 980nm semiconductor laser unit with high power;
- Including 32 sets of synchrotron radiation light source;
- Power and light emission of each welding area can be adjust according to the needs;
- In order to save installation space integrated water cooling structure is used;
- Laser welding equipment has the function of automatic tool change, automatic tool locking and identify the serial number and version of nesting automatically;
- Support 1.4-meter through-type taillights and fixed-side taillights for two cavities welding;
Plastic synchrotron laser transmission welding is to press the plastic parts of the upper layer through near-infrared band and the plastic parts of the lower absorption layer together, through the laser beam energy melting of the lower side material, under the action of pressure and quickly solidified with the upper material; Plastic synchronous laser welding has the advantages of fast welding speed, small thermal stress, small welding deformation, no vibration, dust and high temperature in the welding process, suitable forautomobile,3C electronics and medical industries.
In the design, the outgoing beam is homogenized, and the spot has obvious flat-top distribution
and good uniformity, which is suitable for laser welding of plastics.
Used to support the welding are used for optical structure design of optical fiber orientation and the wedge of light guide plate structure, which is strictly in accordance with our size the positioning of the optical fiber welding efficiency and the uniformity of the energies of the beams test results perform the design, structure design of guide plate to a great extent improve the efficiency of welding, using the characteristics of synchronous welding way is as follows:
- The design of the uniform distribution of each fiber combined with the light guide plate gives the flexibility of 30 welding. The fiber can be freely distributed according to the copy surface of the product to be welded, and the welding stability can be guaranteed;
- The design of light guide plate greatly improves the welding efficiency. Under the condition of ensuring good transmittance, the welding duration is generally about 3-6 seconds;
- The energy concentrated on the welding line can instantaneously melt the underside materials, which can greatly reduce the thermal deformation and internal stress of the welded products when compared with traditional welding;
- Each light source is separately controlled, and the power and light time can be separately controlled according to debugging requirements.
